June 26, 2023

Infrastructure security

The information in this section has been revised. Specifically, we now require TLS 1.2 and we recommend TLS 1.3.

June 24, 2023

Epoch locking and SCTE 35

The guide has been updated to describe a constraint with setting up a channel with epoch locking when an HLS or MediaPackage output group includes SCTE 35 messages. This constraint applies only to epoch locking. It doesn't apply to regular pipeline locking.

June 24, 2023

Data protection

The information in this section has been revised. Specifically, we now require TLS 1.2 and we recommend TLS 1.3.

June 24, 2023

Corrections to delivery to AWS Elemental MediaPackage

The information for using HLS output groups to deliver to MediaPackage using the standard MediaPackage API and using the MediaPackage v2 API have both been revised to correct errors, particularly in the examples for the MediaPackage channel URLs.

May 31, 2023

AWS Elemental Link reorganization

The information about AWS Elemental MediaLive has been reorganized into three main sections, one in Features, one in the setup topics in the navigation bar, and one in the operations topics in the navigation bar.

May 31, 2023

Timecode configuration

The section about timecode has been renamed to timecodes and timestamps. The section has also been revised to clarify how timecode works in MediaLive.

May 22, 2023

Pipeline locking

This section has been revised to clarify some points. Pipeline locking now works with a channel that has multiple inputs (a channel that implements input switching). Inputs must have an embedded timecode. The timecode configuration field in General Configuration for the channel has no effect on pipeline locking.

May 22, 2023

Correction to pipeline locking

This section has been revised to remove incorrect information. Pipeline locking requires an embedded timecode in the input. But you don't need to set the timecode configuration source to embedded. MediaLive always looks for the embedded timecode.

May 22, 2023

Permissions for trusted entity for MediaPackage v2

The information about permissions for the trusted entity has been updated to include the actions required to deliver to an AWS Elemental MediaPackage channel that uses MediaPackage v2. For this delivery, you create an HLS output group.
